Measurements
On July 18, 2003, with the help of Warren Johnson, we measured Utah Railway SD50S 6061 at the railroad's Midvale, Utah engine facility.
It turns out that what we know as the Australian SD50S is 10 inches shorter than the US SD40-2, and 3 feet shorter than the US SD50. The difference appears to be mostly in the truck center measurement.
Below are the numbers, comparing the unit to a UP SD40-2, and with information from the Diesel Spotters Guide, 2000 edition:
